Arduino based current meter with i2c LCD screen

Описание: A simple current meter using the arduino. The schematic is for Arduino UNO/NANO and all the the breadboard tests are made using the NANO. For different scales I've used some push buttons to change between scales. There is also a bit of Ohm Law theory on the video and each part is explained.
